Serial No. 268,787. (No model.)

To all whom it may concern..-

Be it known that I, EARL H. ISRAEL, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Water-Closets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which Figure I is a perspective view illustrative of my invention. Fig. II is an enlarged perspective View of the lever located at the bowl. Fig. III is a similar view showing part of the free end of the lever and showing the opposite side to that shown in Fig. II. Fig. IV is an enlarged perspective view of one of the brackets for securing the rock-shaft to the frame. Fig. V is a section through the water tank, showing the parts within in elevation. Fig. VI is a similar view showing the parts in different position to that shown in Fig. V. The section of the tank in these figures (V and VI) is taken on line VVI, Fig. VIII. Figs. VII and VIII are transverse vertical sections taken on line VII VIII, Fig. V, these two figures showing the parts in different posit-ions. Fig. IX is a detail enlarged section taken on line IX IX, Fig. V. Fig. X is an enlarged elevation or side view of the levers located on top of the tank. Fig. XI is an enlarged section taken on line XI XI, Fig. VI. Fig. XII is an enlarged section showing the outlet-pipe and its valve. Fig. XIII is a vertical section of the inlet-valve.

My invention relates to certain improve ments in waterclosets; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, 1 represents the water-tank,suitably supported above the bowl 2, as shown in Fig. I, and connected thereto by a pipe, 3, which conveys water from the tank to the bowl.

4 represents the pipe through which water enters the tank.

5 represents a lever pivoted to the top of the tank by means of a bracket, 6, and the outer end of this lever is connected by a cord or chain, 7, to the inner end of a lever made in two parts, 8 9. (See Figs. II and III.) The part 8 of the lever is adjustable on the part 9, and is preferably connected to the part by being bent into approximately U shape or zigzag form, as shown at 10, Figs. II and III, so as to form two plates, 10, approximately at right angles to the main portion of the lever, and these plates are perforated, as shown at 11, to receive the outer end of the part 9 of the lever. The part 8 of the lever can thus be moved on the part 9 to regulate the length of the entire lever, and it is held to any adjustment by a set-screw, 12, (see Fig. III,) which passes through the bent portion 10 of the part 8 of the lever and jams against the part 9 of the lever. The inner end of the lever is secured to the front piece, 13, of the frame 14., that surrounds the bowl, by means of a rockshaft, 15, and brackets 16. One of the brackets is shown in Fig. IV, and consists (they are both alike) of a body provided with a hole, 17, to receive connecting-screws, by which they are made fast to the front piece, 13, of the frame 14., and each bracket has a tongue, 18, formed with a loop or outwardly-curved part, 19, forming a socket, 20, to receive the shaft, one of the brackets receiving one end of the shaft and the other the other end of the shaft.

On the part 9 of the lever is secured a pin, 21, that extends up through the top of the frame 14, as shown in Fig. I, and against which the seat 22 presses when forced down. As the seat presses downward on the pin 21, the free end or inner end of the lever is depressed, pulling downward on the cord or chain 7 and operating the lever 5.

I prefer to have a pin 21 on each side of the bowl, and for this purpose I secure a second short lever, 23, (see Fig. II,) to the rockshaft 15, to which a second pin 21 is secured. The cord or chain 7 is secured to the lever by a pin, 7%, held in the lever by a setscrew, 7 so that it may be adjusted to allow the cord or chain to be moved to one side to clear any obstruction.

The part 9 of the lever 8 9 is preferably made in two parts-a main part and a short part, (next to the'shaft.) The short part has lips 25, by which and rivets 26 the parts are secured together. The main part is preferably made of steel to afford strength and rigidity and the short part of cast-iron, which may be cast with a hub, through which the shaft 15 passes.

The seat 22 is preferably provided with metal plates 27, bearing on the pins 21 when the lid to the tank.

50 ablejoint between the two parts.

or cover is depressed. These plates are countersunk at 27 to receive the upper ends of said pins, so as to prevent unnecessary movement of the parts relatively to one another, and consequently the disagreeable screeching noise that would otherwise occur.

The pipe 3 is connected with one leg, 30, of a pipe, 31, within the tank 1. This leg 30 has a neck, 32, extending beneath the bottom of This leg 30 of the pipe is also provided with a .hollow enlargement, 32, (see Figs. VII and XII,) which forms the seat for a valve, 33, and through which the water passes from the tank to the bowl when the valve 33 is opened. The valve, preferably, consists of a disk or plate, 34, provided with a packing-ring, 35, and pivoted to the leg 30 at 36 by means of an arm, 37, to which the disk is connected by a suitable screw, 38.

To the free end of the arm 37 is connected the lower end of a rod, 39, as shown at 40. The upper end of the rod 39 is connected to the inner free end of a lever, 41, pivoted at 42 to a projection, 43, formed upon the bracket 6, secured to the top of the tank. The upper end of the rod 39 simply passes through a hole made in the free end of the lever 41,.and it is screw-threaded to receive a nut, 45, above the lever. This connection permits of an adjust- (See Fig. X.) The inner end of the lever 41 is connected by a link, 46, to the lever 5. This is also best shown in Fig. X. When the lever 5 is pulled down by lowering the seat 22, as stated, the lever 41 is moved from the position shown in full lines, Fig. X, to the position shown in dotted lines, same figure, and as this takes place the valve 33 is lifted or opened from its seat, as shown in Fig. VIII, and water passes through the portion 32 of the leg 30 and down 0 first part of the movement of the lever 5,the seat 22 at this time not being entirely down. As the seat continues to move downward and the free end of the lever 5 is raised, the link 46 is moved over to the position shown by dotted lines 49, Fig. X, and in making this movement it forces the lever 41 back from the position shown in dotted lines, Fig. X, to the position shown in full lines and again closes the valve 33, the siphonic flow having now been effected and the water continuing to run through the legs 47 and 30. The water thus continues to run until the siphon is brokem and this is done by means ofa valve, 50, securedtoa head, 51, pivoted at 52 to a T-pipe, 53, on the upper ends of the legs 30 and 47. This valve 50 controls one month of the T, and it is provided with a stem, 54, to

which is secured a float, 55, by a stem, 56, the stem 56 of the float being held on the stem 54 of the valve by a collar, 57, and a set-screw, 58. The float holds the valve 50 closed until the amount of water in the tank is reduced or has run out sufficiently to allow the float to drop, and as it drops it opens the valve 50, admitting air and breaking the siphon. The high-water mark in the tank is shown by dotted line 59, Fig. V, and the low-water mark is shown at 60, Fig. V. The valve 50 is shown closed in Fig. Vand open in Fig. VI. The water that passes out after the opening of the valve 33 and before the opening of the valve 50 produces what is called the fore-wash. When the water in the tank has been reduced, as shown in Fig. VI, sufficiently to allow the valve 50 to open by the falling of the float 55, the discharge of water through the pipe 3 ceases, as stated, and the tank is resupplied through the pipe 4, which is automatically opened by a float, 61. This float has a stem, 62, the lower end of which is pivoted at 63 to the housing 64 of a valve, 65. The valve 65 (see Fig. XIII) has a stem, 66, and with its stem the end of the stem 62 of the float 61 engages. The valve 65 seats upon a plug, 67, which connects the supply-pipe to the tank 1. Now the falling of the float 61 opens this valve 65 by lifting it through the described connection, and the water flows from the pipe 4 into the tank 1 through a spout, 63, on the housing 64 of the valve. As the water thus flows, (in supplying the tank again,) the valve 50 is closedby the water lifting the float 55, so that a siphon may again be created within the legs 30 47 of the pipe 31. As the tank fills with water, the float 61 also rises and automatically closes the valve 65. This describes the working of the apparatus as the seat 22 is forced down upon its support, and the forewash is effected as described. Now when the weight on the free end of the lever 5. As the lever makes this movement, the lever 41 is first raised to the position shown in dotted lines in Fig. X, (as when thelever is moved in the act of lowering the seat,) thus opening the valve 33, and then the lever 41 goes back to the position shown in full lines, Fig. X, and the valve 33 is closed. This starts the siphon again and the water commences to flow through the legs 47 and 30 of pipe 31 into the pipe 3 and through the bowl. This flow of the water gives the after wash and has a longer duration than the flow of the fore-wash. This flow of the water continues until the siphon is broken by a valve, 70, controlling the other end of the T 53 to that controlled by the valve 50. This valve 70 is pivoted at 71 to the T at 72, and has a stem, 73, to which is connected a depending rod, 74. On the rod 74 is a float, 75, held .to any desired adjustment by means of a set-screw, 76. The lower end of the rod is held and guided by an arm, 78, projecting from the legs 30 47. Thus when the water in the tank has flowed sufiiciently long to give the desired Wash and is lowered in the tank to at or near the elevation shown at 60, Fig. V, the float 75 opens the valve 70 and breaks the siphon, and the water ceases to run through the legs. As the water thus lowers, the valve 65 is again opened and water flows in to refill the tank, as already de scribed. The flow of water into the tank is of course not as great as the outflow, so that the inlet of water is not sufficient to prevent the decrease in the amount of water in the tank while the siphon remains unbroken. As the tank is supplied with Water again through the valve 65, the float 75 rises,closing the valve 70, affording an opportunity for the siphon to be again started when the seat 22 is again lowere In order to produce the long after-wash it is of course necessary that the valve be held shut at this time, or after the lever 5 assumes its normal position. This is accomplished by forming an arm, 79, on the stem 54, which extends inward beyond the pivot 52 and beneath a lever, 80, provided with a weight, 81, and pivoted at 82 to a projection, 83, extending upward from the bracket 6. When the outer end of the lever 5 is lowered in the act of lowering the seat 22, a projection, 84, thereon comes against the outer end, 85, of the lever 80 and forces the inner end of the lever upward, as shown in Fig. VI, thus disengaging it from the extension 79 of the stem 54 and allowing the valve 50 to open. When the le ver 5 comes back again to its normal position, the projection 84 is removed from the end 85 of the lever 80 and the weight 81 brings the lever down against the extension 79 of the stem 54, and thus holds the valve 50 closed, this pressure being greater than the weight of the float 55. The valve 50 is thus held closed during the after-wash, so that the siphon is not broken by the opening ofit, but continues until the valve 70 opens, the float 75 of which is on a lower elevation than the float 55 of the valve 50. I thus accomplish the desirable fore and after wash of different durations.

To insure a supply of water in the bowl after the long wash, I provide means which will allow a small amount of water to flow in when the siphon, after a long wash, has been broken. This I produce by forming a short tube or pipe, 90, on the leg 30 of the pipe 31, and pivot to this tube a valve, 91, having a stem, 92, to which is connected a rod, 93, provided with a float, 94. Before the valve 70 is opened to break the siphon this valve 91 is opened, (the float 94 being at a higher elevation than the float 75,) and the water flows through this tube or pipe 90, and continues to flow after the valve 70 is opened and the siphon broken, and until the supply of water to the tank lifts the float 94 and closes the valve 91.

The stem 62 of the float 61 is preferably made in two parts to afford an adjustment of the float so as to make the valve 65 open sooner or later. The two parts are preferably connected, as shown in Fig. X[that is, a disk or head, 100, is formed on the adjacent ends of the two parts of the stem and are connected by a set-screw, 101. Between the two disks is placed a leather or other suitable washer, 102, to give the necessary friction to prevent the parts from turning on each other when the set screw 101 is tightened. This gives a simple and easy method of regulating the height of the float 61, and is superior to the method of simply bending the stem 62, as heretofore practiced.

The construction of the valves 50 and is preferably that shown in Fig. IX, each valve being composed ofa plate or disk, 105, with a stem, 106, passing through the part to which the valves are secured. The disk ofeach valve has a marginal flange, 107, turned slightly in ward at l08,and within this flange fits a leather, rubber, or other disk, 109, which, when the valve is closed, bears against the mouth of the T 53. The area in the enlargement 32 of the opening of the valve 33 is made larger than the area of the pipe 3, the object being to allow a large amount of water to enter the moment the valve is opened to insure the forma tion of a siphon, though the valve remains open but an instant.
